The O-57554- unit is classified as a Shark Interface module that was created to be used in the line of programmable logic controllers known as AutoMax, which was created by Reliance Electric. The O-57554- Shark Interface module is not being produced by its OEM anymore, but AX Control regularly has it in stock.
The O-57554- Shark Interface module is comprised of two main components: its faceplate and its printed circuit board. The module’s faceplate consists of a 9-pin female D-shell connector, which has the label “NETWORK” printed above it, and two green status indicator LEDs. The top LED, which has the label “CPU OK” printed above it, lets the operator know that the module has successfully undergone its power-up diagnostic routine and it working as intended. Below that, there is the other LED, which is labeled as “COM OK,” that lets the operator know that the module is communicating properly with the Remote I/O network. Be aware, though, that this LED will begin flashing whenever an invalid drop number has been selected on the rotary switch below it. The rotary switch has sixteen positions that can select drop positions of 1 to 7 or 9 to F. In the event that you need to change the drop number for the rack, then you will need to alter the setting of the rotary switch and the cycle the power for the module. Upon power-up, the rotary switch is in read-only mode.
The O-57554- Shark Interface module has a microprocessor that is used to connect with the backplane of the Shark rack by use of the timing and buffer circuitry. The power for the logic circuitry is supplied by use of the rack’s +5 VDC power supply. The power that is to be used on the module’s remote I/O network driver is supplied by use of the Shark rack’s +24 VDC power supply and is regulated at +12 VDC in total.
